根据1998年5月~1999年2月在闽东北外海26°00′~28°00′N,125°30′E以西海域的虾类资源调查资料,分析了假长缝拟对虾(Parapenaeus fissuroides)的数量时空分布和生物学特性。结果表明:假长缝拟对虾平均资源密度指数以春季最高,达3.52 kg/h,秋季、冬季和夏季均较低,分别为2.00 kg/h、1.86 kg/h和1.75 kg/h。密集区主要分布在26°30′~28°00′N,121°30′~124°00′E,水深80~100m一带海域,26°30′以南资源密度较低。假长缝拟对虾体长分布范围为55~121mm,平均体长为82.3mm,雌性个体平均体长84.9mm,雄性为78.6mm,雌性个体明显大于雄性个体。雌性初次性成熟个体最小体长为83mm,体重为5.5g,大量性成熟体长范围为91~110mm,体重范围为8.0~12.0g。目前该海域假长缝拟对虾资源尚具一定利用潜力。
According to the survey data of shrimp resources in the waters west of 26 ° 00’28 ° 00’N and 125 ° 30’E in the northeastern Fujian province from May 1998 to February 1999, the genetic diversity of the shrimp (Parapenaeus fissuroides) The number of spatial and temporal distribution and biological characteristics. The results showed that the average resource density index of Pseudoperonospora crassa was the highest in spring, reaching 3.52 kg / h in spring, 2.00 kg / h, 1.86 kg / h and 1.75 kg / h in autumn, winter and summer respectively. The dense areas are mainly distributed in the sea areas of 26 ° 30 ’~ 28 ° 00’N, 121 ° 30’ ~ 124 ° 00’E and the water depths of 80 ~ 100m, while those of the south of 26 ° 30 ’are lower. The body length distribution of pseudopapteen was from 55 to 121 mm with an average body length of 82.3 mm. The average body length of females was 84.9 mm and the male was 78.6 mm. The females were significantly larger than the male ones. Female first sexual maturity of the smallest body length of 83mm, weighing 5.5g, a large number of mature body length range of 91 ~ 110mm, body weight range of 8.0 ~ 12.0g. At present, the marine pseudohyphae resources have certain use potential.
